Contracts/Offer

Offer and acceptance analysis is a tool used to determine whether a contract exists between two parties.

There must be an express or implied agreement. In modern practice, whether there has been an agreement is determined objectively, not subjectively. Thus, it is no defense to an action based on a contract for the defendant to claim that he never intended to be bound by the agreement if under all the circumstances it is shown at trial that his conduct was such that it communicated to the other party or parties that the defendant had in fact agreed. Signing of a contract is one way a party may show his assent. Alternatively, an offer consisting of a promise to pay someone if the latter performs certain acts which the latter would not otherwise do (such as paint a house) may be accepted by the requested conduct instead of a promise to do the act. The performance of the requested act indicates objectively the party's assent to the terms of the offer.

The essential requirement is that there be evidence that the parties had each from an objective perspective engaged in conduct manifesting their assent. This manifestation of assent theory of contract formation may be contrasted with older theories, in which it was sometimes argued that a contract required the parties to have a true meeting of the minds between the parties. Under the "meeting of the minds" theory of contract, a party could resist a claim of breach by proving that although it may have appeared objectively that he intended to be bound by the agreement, he had never truly intended to be bound. This is unsatisfactory, as the other parties have no means of knowing their counterparts' undisclosed intentions or understandings. They can only act upon what a party reveals objectively to be his intent. Hence, an actual meeting of the minds is not required.

A contract will be formed (assuming the other requirements are met) when the parties give objective manifestation of an intent to form the contract. Of course, the assent must be given to terms of the agreement. Usually this involves the making by one party of an offer to be bound upon certain terms, and the other parties' acceptance of the offer on the same terms. The acceptance of an offer may be either a statement of agreement, or, if the offer invites acceptance in this way, a performance of an act requested in the terms of the offer. For instance, if one tells a neighbor kid that if the kid mows the offeror's lawn, the offeror will pay $20.00, and the kid does mow the lawn, the act of mowing constitutes the manifestation of the kid's assent. For a contract based on offer and acceptance to be enforced, the terms must be capable of determination in a way that it is clear that the parties assent was given to the same terms. The terms, like the manifestation of assent itself, are determined objectively. They may be written, or sometimes oral, although some kinds of contracts require a writing as evidence of the agreement to be enforced.
